Underfloor heating with carpets – How does it work?

When it comes to making a space truly cosy, we understand that you want it to be as warm as possible, especially in winter months. Carpets are a great way to realise this, providing a more comfortable under-foot experience than most other flooring materials, which can become stone-cold without underfloor heating, and certainly do not look as inviting, especially in spaces such as bedrooms.  

It may, therefore, seem like an attractive option to combine carpet with under floor heating for maximum comfort and warmth within your home, at the same time as boosting its overall aesthetic. But does underfloor heating work with carpet, and is it even possible to combine the two? That’s exactly what this expert guide is going to explain. 

Is carpet compatible with underfloor heating? 

So, can you have underfloor heating with carpet? The short answer is yes, but there are a few things that you should consider when deciding to blend these two home comforts. 

Natural stone flooring and tiles are the best options when it comes to underfloor heating, whilst carpet sits (perhaps) on the least preferable end, but that doesn’t mean you can’t or shouldn’t do it. When combining underfloor heating with carpet, it is therefore essential that you select the appropriate type of carpet so that you do not compromise either material or reduce its effectiveness. 

What types of carpet are suitable for underfloor heating? 

When deciding on a suitable carpet covering for underfloor heating, there are several things that you should bear in mind. Firstly, consider the overall thickness of the carpet. If it is too thick, then it is going to simply insulate your underfloor heating system, and you won’t receive any of its benefits. Similarly, it is recommended that you select a carpet with a hessian backing (as opposed to rubber), which will allow heat to travel through your carpet. Rubber, on the other hand, will act as an insulator and will compromise the effectiveness of your underfloor heating system. 

Underfloor heating and carpet tog ratings 

The suitableness of the carpet when paired with an underfloor heating system can be deciphered by looking at your carpet’s tog rating, which is a measure of thermal resistance. Simply put, the combined value of the carpet and underlay should not exceed 2.5 tog, and preferably less than 1.5 for systems with a heat pump. 

Installing a carpet over underfloor heating 

There are several things to consider when installing your carpet over an underfloor heating system. For example, ensure that the overall tog does not exceed 2.5, and make sure that your floor is structurally dry and sound. It is also important to make sure that any chemicals on the floor (such as sealants) are compatible with your carpet’s underlay, and you should remove any paint, debris, or dust before setting it down.
